Abstract: A flat wrapping or package, e.g., for film sheets, particularly sheets of X-ray film, in which the margins of one web of wrapping material are folded inwardly over the edge margins of a narrower web of wrapping paper with the film sheets sandwiched in between, the contacting web portions are adhered together, and cut edges are sealed together. Each exterior web fold edge is creased along two closely spaced parallel lines spaced apart approximately the thickness of the wrapped film sheet so as to impart to the opposite side edges of the wrapping a generally concave configuration between an upper and lower corner.

Abstract: A package for packaging a stack of articles in sheet form comprises at least two strips which are overlappingly sealed to each other, so forming a loosely overlying edge which greatly facilitates opening of the package. The whole may be provided with protective sheets at both sides of the stack, whereby said protective sheets may have a row of perforations at the edge of the composing strips so that the first sheet of the stack may easily be taken from the stack after removing part of the protective sheets.

Abstract: Hermetically sealed package for photographic sheet materials provided with one or two tearstrips which extend at the end of the package in the form of a loop. In order to facilitate the opening of the package in the dark a small part of the package is scored in the corners where the tearstrip extends, so that it can easily be torn off whereupon a sufficiently long extremity of the tearstrip is freed to open the package without difficulty.
